METAL CORNER FOR BOXES.

Specification of Letters Patent.

Application filed December 10, 1915. Serial No. 66,140.

To all whom it may concern Be it known that I, Isroonn M. HnsoHnLEs, a citizen of the United States of America, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Metal Corners for Boxes, of which the fol-' lowing is specification, reference being had therein to the accompanying drawing.

This invention relates to a reinforcement for paste board boxes or boxes made of thin wood, or the like, which is adapted to be carried by the corners thereof for efliciently reinforcing the box.

Another object of this invention is the production of a metal corner for boxes which is so constructed as to be quickly applied at the corner portions of a box, thereby reinforcing the box, preventing its opening when in transit or resisting any tendency thereof to be turned or otherwise injured when in use, whereby the life of the box will be greatly prolonged, while the contents thereof will be prevented from spillingor becoming disengaged Another object of this invention is the production of a metallic plate which is so constructed as to constitute a metal reinforcement for the corner of a box, this plate being provided with a plurality of struck out spurs which are adapted to pass through the walls of the box for eiiiciently retaining the metal plate in engagement therewith, these spurs being provided with a clamping portion which will retain the plate against side movement when upon the box, thereby preventing the portions of the spurs which pass through the walls of the box from wearing or cutting the walls.

lVith these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a detail perspective view of the metal corner or plate, illustrating the manner in which the same is used. Fig. 2 is a horizontal section through the plate which constitutes the metal corner, a box being shown in section and partially broken away, the manner in which the plate is retained being clearly shown. Fig. 3 is a front plan of the plate, illustrating the same before being bent upon its central vertical axis. Fig. 4 is ,aplan view of the blank from which the metal plate constituting the reinforcement is formed.

Referring to the accompanying drawing by numerals it will be seen that the metal corner for boxes comprises a metallic plate which discloses a body 1, which is preferably rectangular, as shown in Figs. 3 and i. This body 1 is bent along the dotted line 2 so as to have a substantially L-shaped construction after being bent, whereby the plate may be easily positioned upon the corner of a box for reinforcing the same, as clearly shown in Figs. 1 and 2. The body 1. is provided with a pair of substantially V-shaped spurs 3, the base portions of which are formed adjacent the ends of the body 1 allowing the points at of the spurs to extend toward the central portions of the body 1 before the same are bent outwardly." These spurs are first bent along the dotted lines 5 so as to be passed through the side walls 6 of a box. After being passed through the side walls 6, the points a are bent toward the end portions of the body 1 so as to extend in opposite directions to each other, as clearly shown in Figs. 2 and 3. It will be noted by referring particularly to Figs. 2 and 3 that the points 4 of the spurs .3 extend for a considerable distance beyond, the end portions of the body 1 so as to allow the spurs to be efiiciently and positively clamped in position upon the walls 6. of the body. By taking any suitable instrument and clamping these spurs it will be seen that they will first be clamped so as to cause their ends to di-ginto the side walls 6 of a box.

Patented J an. 16, 1917.

Since the plate, however, is formed of sheet metal, it is, of course, obvious that the spurs will spring outwardly for a short distance but this springing movement will be just enough to allow the spurs to fit snugly upon the inner sideportions of the walls 6. If these spurs terminated evenly with the end portions of the bodyl it would be impossible M to clamp the points of the spurs into the side walls of the box, since the pressure would be directly against the body 1. Since, however, as above set forth, these spurs extend for a considerable distance beyond the ends of the body 1 this clamping action would only be against the resistance of the strength of the side walls 6 of the box and consequently these side walls would give so as to allow the clamping action above set forth to take place. a

It will be noted by referring to the draw ing that the spurs 3 are not bent toward the openings 3 throughout their entire length but are provided with an offset portion 7 which although it extends in a plane parallel to the side portions of the body 1, is offset inwardly as shown most clearly in Fig. 2, so as to extend in a plane parallel to but at a distance from the inner surface of the body 1. Consequently, it will be seen, as shown clearly in Fig. :2, that the side walls 6 of the box are clamped very tightly or more so than at the other portions of the spurs for efiiciently and securely retaining the plate in a set position upon the side walls 6 of the box. This clamping action adjacent each end of the body 1 will hold the body against side movement upon the sides If this clamping construction were not provided it is obvious that a foreign object which might strike the side edges of the body 1 when the plate is in use would tend to drive the plate sidewise. If the clamping action as above set forth which is caused by the offset portion 7 was not provided the full force of the plate upon the side edge of the body would be taken up by the side edges of the spurs where the spurs pass through the walls 6 of the box. Since these spurs are of sheet metal as is thebody 1 their tendency would be to cut the paste board so that in the course of a comparatively short while the ordinary usage of the reinforcement upon a box corner would be 'to cause the body to become loose, thereby lessening its efiici'ency. Under such conditions it would be of comparatively little use and, therefore, it is necessary to provide some means for permanently retaining the plate in a set position upon the sides 6 of the box, thus causing the plate to actually reinforce the corners of a paste board box or a thin wood box as long as the life of the box'would permit, without any danger whatever of the plate injuring the box as is caused by the ordinary corner plates and reinforcements now in use.

From the foregoing description it will be seen that a very simple and eflicient metal corner for boxes has been provided which is constructed so as to constitute a reinforcement for the corners so that after being positioned upon the corners of a box the spurs may be clamped in position so as to positively prevent the accidental displacement of the body under any circumstances whatever, while the spurs are so clamped as to hold the body upon the corner of a box without danger of injury thereto, thus causing the metal corner to produce the maximum amount of eliiciency.

Vhat is claimed is:

1. As a new article of manufacture a metal corner for boxes comprising a body, said body being bent along its central vertical axis so as to constitute a substantially L-shaped structure in longitudinal section, whereby said body will fit snugly upon the side corners of a box, V-shaped spurs struck from said body, the bases of said spurs being adjacent the ends of said body, the points of said spurs being adapted to be passed through the side walls of a box and then being bent so as to extend beyond the ends of said body, each spur being provided with an offset portion adjacent its base, said offset portion extending in a plane parallel to but at a distance beyond the inner portions of said body, whereby an increased binding action is presented adjacent each end of said body between the side portions and the major portions of said spurs, whereby the side movement of the body when positioned upon the side walls of a box will be prevented, thereby preventing thevside edges of the spurs from cutting the side walls of the body' which action would cause the body to become loose when in use, thus rendering it inefficient in operation.

2. As a new article of manufacture a metal corner for boxes comprising a body, said body being adapted 'to be positioned upon the corner of a box, spurs struck from said body, said spurs being adapted to be passed through the side walls of a box and be clamped so as to extend in planes parallel to the inner portions of said body, oifset portions formed adjacent the bases of said spurs, the distance between the offset portions of said spurs and the main portions of said spurs being less than the distance between the body portion and the main portion of said spurs, whereby an increased binding action is presented upon the side walls so as to securely hold the body in a set position and prevent its accidental injury upon the side walls of a box, whereby the i life of the box may be greatly prolonged as long as the body renders its maximum amount of efliciency.

In testimony whereof I hereunto affix my signature.
